Mepolizumab in allergic bronchopulmonary aspergillosis complicated by infection.

Allergic bronchopulmonary aspergillosis (ABPA) is an allergic reaction caused by the fungus Aspergillus, and it is often treated with steroids or antifungal agents. However, long-term use of these medications can lead to infections and drug interactions. We present the case of a 71-year-old woman with ABPA who was diagnosed with hepatitis B and active hepatitis C, and sputum analysis revealed the presence of bacteria. Oral steroids were initially administered, but the patient was switched to mepolizumab because of numerous infectious complications. The early introduction of mepolizumab is effective in patients with ABPA complicated by infectious diseases.

Complete Regression of Endobronchial Carcinoid Tumor after an Endoscopic Biopsy.

An 80-year-old woman who had been diagnosed with an endobronchial carcinoid tumor visited our hospital for treatment with an endoscopic technique. However, a bronchoscopic examination at our hospital showed spontaneous regression of the tumor at the orifice of the right middle lobar bronchus. Chest computed tomography five months later revealed no local recurrence. This is the second report of an endobronchial carcinoid tumor vanishing after an endoscopic biopsy.

Novel prospective umbrella-type lung cancer registry study for clarifying clinical practice patterns: CS-Lung-003 study protocol.

INTRODUCTION: Conventional cancer registries are suitable for simple surveillance of cancer patients, including disease frequency and distribution, demographics, and prognosis; however, the collected data are inadequate to clarify comprehensively diverse clinical questions in daily practice. METHODS: We constructed an umbrella-type lung cancer patient registry (CS-Lung-003) integrating multiple related prospective observational studies (linked studies) that reflect clinical questions about lung cancer treatment. The primary endpoint of this registry is to clarify daily clinical practice patterns in lung cancer treatment; a key inclusion criterion is pathologically diagnosed lung cancer. Under this registry, indispensable clinical items are detected in advance across all active linked studies and gathered prospectively and systematically to avoid excessive or insufficient data collection. Researchers are to input information mutually, irrespective of the relevance to each researcher's own study. Linked studies under the umbrella of the CS-Lung-003 registry will be updated annually with newly raised clinical questions; some linked studies will be newly created, while others will be deleted after the completion of the analysis. Enrollment began in July 2017. DISCUSSION: We successfully launched the umbrella-type CS-Lung-003 registry. Under this single registry, researchers collaborate on patient registration and data provision for their own and other studies. Thus, the registry will produce results for multiple domains of study, providing answers to questions about lung cancer treatment raised by other researchers. Through such analysis of each linked study, this registry will contribute to the comprehensive elucidation of actual daily practice patterns in lung cancer treatment. KEY POINTS: CS-Lung-003 registry directly integrates multiple linked studies created under the umbrella of this cancer registry to solve various clinical questions regarding daily practice patterns of lung cancer treatment.

Coronavirus Disease-19 Pneumonia with Facial Nerve Palsy and Olfactory Disturbance.

The novel coronavirus disease-2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus-2, has spread worldwide from China. There are no case reports from Asia of COVID-19 with facial paralysis and olfactory disturbance. We herein report a case of COVID-19 pneumonia in a Japanese woman who showed facial nerve palsy and olfactory disturbance.

[A CASE OF NON-TUBERCULOUS MYCOBACTERIOSIS WITH PLEURAL EFFUSION AND THICKENING IN A PATIENT WITH AN OCCUPATIONAL HISTORY OF ASBESTOS EXPOSURE].

We report a case of a 75-year-old man with pleural effusion and an occupational history of asbestos exposure. Fluorodeoxyglucose positron emission tomography-computed tomography (FDG-PET/CT) examination revealed FDG up-takes along his pleura, leading to an initial suspicion of pleural mesothelioma. Pathological findings of a diagnostic video-associated pleural biopsy showed epithelioid cell granuloma. Repeated sputum cultures were positive for Mycobacterium intracellulare. The patient was diagnosed with pleuritis caused by non-tuberculous mycobacteria (NTM). NTM should be considered a potential cause of pleuritis.

A case of pulmonary mucoepidermoid carcinoma responding to carboplatin and paclitaxel.

A 59-year-old man was admitted to our hospital with dyspnea and cough. A large polypoid tumor was observed in the lower trachea and bronchoscopic polypectomy was performed using a snare to relieve symptoms. The tumor was diagnosed as a high grade mucoepidermoid carcinoma mainly by the histology of piecemeal specimens obtained by bronchoscopic resection. The primary lesion involved the trachea and the main bronchus, and there were multiple metastases in the lung. The patient was treated with the combination of carboplatin and paclitaxel. After four cycles of chemotherapy, the tumors were significantly reduced. He remains well without evidence of tumor progression for 25 months. This case suggests that the combination chemotherapy of carboplatin and paclitaxel can be an option for treatment of pulmonary mucoepidermoid carcinoma.

Benefits and adverse events among elderly patients receiving concurrent chemoradiotherapy for locally advanced non-small cell lung cancer: analysis of the Okayama Lung Cancer Study Group trial 0007.

INTRODUCTION: Thoracic radiotherapy (RT) with concurrent chemotherapy may be offered to selected elderly patients with locally advanced non-small cell lung cancer. The Okayama Lung Cancer Study Group (OLCSG) 0007 trial with patients up to 75 years showed that with concurrent RT, docetaxel and cisplatin (DP) chemotherapy was an alternative to mitomycin C, vindesine, and cisplatin (MVP) chemotherapy. METHODS: Of the 99 patients in the DP arm, 73 were younger than 70 years and 26 were 70 years or older. Of the 101 patients in the MVP arm, 75 were younger than 70 years and 26 were 70 years or older. Overall survival (OS) and progression-free survival (PFS) were calculated using the Kaplan-Meier method and were compared using an early period weighted log-rank test. Toxicities and treatment intensities were compared by χ(2) and t tests, respectively. RESULTS: OS and PFS tended to be longer in the DP arm versus MVP arm: median OS (months), 27.5 versus 22.9 (p = 0.109) and 25.6 versus 23.4 (p = 0.064) in the ≥70-year and <70-year groups, respectively; median PFS (months), 19.0 versus 11.5 (p = 0.175) and 12.0 versus 9.3 (p = 0.132) in the ≥70-year and less than 70-year groups, respectively. Severe toxicity (neutropenia, esophagitis, and pneumonitis) rates did not differ between age groups. Nevertheless, the absence of statistically significant differences in this retrospective analysis might be due to the small number of patients. Radiation intensity was similar between the groups, but chemotherapy intensity was lower in the ≥70-year group. CONCLUSION: Chemotherapy with concurrent RT may be effective and tolerable in elderly patients with locally advanced non-small cell lung cancer.

Comparison of the incidence and pattern of interstitial lung disease during erlotinib and gefitinib treatment in Japanese Patients with non-small cell lung cancer: the Okayama Lung Cancer Study Group experience.

BACKGROUND: Data comparing the incidence and pattern of interstitial lung disease (ILD) in non-small cell lung cancer patients receiving treatment with gefitinib versus erlotinib, both of which are epidermal growth factor receptor tyrosine kinase inhibitors, are scarce. We investigated the incidence of ILD in Japanese patients treated with gefitinib or erlotinib. METHODS: We reviewed the clinical records of 209 patients treated with erlotinib in 2008 (cohort A) and 330 treated with gefitinib between 2000 and 2003 (cohort B). Toxicity within the first month of treatment was investigated. RESULTS: The patients in cohort A had fewer known risk factors for ILD (e.g., poor performance status and prior pulmonary fibrosis). ILD was detected in two patients (1.0%) from cohort A and eight patients (2.4%) from cohort B during the first month of treatment. The events were graded as follows: one patient each in grades 1 and 2 (cohort A), and one, one, and six patients in grades 3, 4, and 5, respectively (cohort B). Multivariate analysis revealed that poor performance status and prior pulmonary fibrosis were significantly correlated with the occurrence of ILD, but the type of epidermal growth factor receptor tyrosine kinase inhibitor administered was not. CONCLUSION: There was a somewhat lower incidence of ILD with erlotinib therapy than with gefitinib therapy, despite no statistically significant difference. Patient selection based on awareness by Japanese physicians of the risk factors for ILD, rather than the type of agent, may explain the difference in ILD incidence between the two treatments.

Sex difference in the influence of smoking status on the responsiveness to gefitinib monotherapy in adenocarcinoma of the lung: Okayama Lung Cancer Study Group experience.

BACKGROUND: Gefitinib is effective in patients with lung adenocarcinoma. Smoking status also affects the responsiveness to gefitinib, but it has not been fully evaluated whether a sex difference exists in the influence of smoking on the efficacy of gefitinib in patients with lung adenocarcinoma. METHODS: We reviewed the clinical records of 260 Japanese patients with lung adenocarcinoma who received gefitinib therapy (250 mg/day), and whose smoking status was known. Tumour response and survival were evaluated and stratified by smoking status and gender. RESULTS: Among the 260 patients, 157 were male (60%). Median pack-years was 40 (range 8-160) and 23 (range 1-74) in male and female smokers, respectively. Objective response was observed in 62 (23.8%) of the 260 patients, and 1-year overall survival and progression-free survival were 45.1 and 24.3%, respectively. Multivariate analysis revealed that smoking status (pack-years) was an independent predictive factor for response to gefitinib [odds ratio (OR) = 0.971, 95% confidence interval (CI) = 0.947-0.995; P = 0.0159] in male patients, but not in female patients (OR = 0.999, 95%CI = 0.957-1.042). Additionally, pack-years significantly influenced the overall survival in males (hazard ratio = 1.010; 95%CI = 1.002-1018, P = 0.0169), while differential survival of females was not significantly predicted by this factor (P = 0.7639). CONCLUSIONS: In male patients with lung adenocarcinoma, cumulative smoking significantly affected response and survival following gefitinib treatment, while in female patients, responsiveness to gefitinib was independent of smoking status. These results suggest that the influence of smoking habit on responsiveness to gefitinib is gender specific.

Interstitial lung disease in Japanese patients with non-small cell lung cancer receiving gefitinib: an analysis of risk factors and treatment outcomes in Okayama Lung Cancer Study Group.

UNLABELLED: Risk factors for the development of interstitial lung disease in patients with non-small cell lung cancer receiving gefitinib and the prognostic factors after interstitial lung disease development have not been established. The aim of this study was to retrospectively identify and evaluate these possible factors. PATIENTS AND METHODS: We reviewed the clinical records and radiographs of 365 consecutive patients with non-small cell lung cancer who received gefitinib in West Japan between 2000 and 2003. RESULTS: In total, 330 patients were eligible for interstitial lung disease evaluation, and 15 patients (4.5%) were finally confirmed to have developed interstitial lung disease by blinded expert review. Multivariate analysis revealed that preexisting pulmonary fibrosis, poor performance status, and prior thoracic irradiation were independent risk factors for interstitial lung disease, with odds ratios of 21.0 (95% confidence interval, 5.12-86.3, P < 0.0001), 9.70 (2.27-41.4, P = 0.001), and 4.33 (1.27-14.8, P = 0.019), respectively. Among the 15 patients who developed interstitial lung disease, eight have died of the condition. Short interval from the initiation of gefitinib treatment to the onset of interstitial lung disease, acute interstitial pneumonia pattern, and the presence of pre-existing pulmonary fibrosis were associated with poor prognosis. DISCUSSION: Our results suggest the importance of patient selection for gefitinib treatment based on interstitial lung disease risk factors in the Japanese population identified.

[A case of carcinomatous lymphangitis of the lungs due to stomach cancer responding to TS-1].

We report a case of carcinomatous lymphangitis of the lungs due to and stomach cancer showing remarkable response to TS-1. The patient was a 51-year-old man whose chest x-ray and computed tomography (CT) revealed lymphangitis, and endoscopic examination showed stomach cancer on posterior wall of stomach body. Bone marrow metastasis was suspected because platelet count was 50/microliter, and myelocytes and metamyelocytes emerged in peripheral blood. TS-1 80 mg/day was administered orally for 28 days as 1 course. After 4 courses of TS-1, chest x-ray showed remarkable improvement, and platelet count was normalized. The patient survived for 10 months after the first visit. We suggest that TS-1 is an effective therapy for carcinomatous lymphangitis of the lungs due to stomach cancer.

[Case of pulmonary tuberculosis in late stage of pregnancy].

A 28-year-old woman who was a nurse was admitted to our hospital because her sputum was positive for M. tuberculosis. She was pregnancy of 35 weeks. First, she was administered INH, RFP, PZA and was treated with cesarean section on the 21st day after starting tuberculosis chemotherapy. The operation was done in operating room of negative pressure ventilation. The patient returned to the tuberculosis ward, and the newborn infant entered to a newborn nursery room after confirming negative tubercle bacilli in amnionic fluid by PCR examination. EB was added to the regimen of chemotherapy after childbirth. In general hospitals, infection control is an important issue as seen in this case.

Phase I/II study of altered schedule of cisplatin and etoposide administration and concurrent accelerated hyperfractionated thoracic radiotherapy for limited-stage small-cell lung cancer.

To improve the efficacy of a combination of cisplatin and etoposide and concurrent accelerated twice-daily thoracic radiotherapy against limited-stage small-cell lung cancer, we conducted a phase I/II study using an altered schedule of chemotherapy administration. Chemotherapy consisted of four cycles of cisplatin (days 1 and 8) and etoposide (days 1, 2, 8, and 9) every 4 weeks. Accelerated hyperfractionated thoracic radiation (1.5 Gy twice daily x 30 fractions, total dose of 45 Gy) was concurrently given with the first cycle of chemotherapy. The recommended doses of cisplatin and etoposide determined in the phase I study were 40 and 80 mg/m(2), respectively. In the phase II study, the overall response rate was 100% (complete response: 32%, partial response: 68%). By a median follow-up time of 29 months, median radiation-outfield progression-free survival was 13.4 months, while radiation-infield progression-free survival did not reach median value. The median overall survival time was 22.9 months, with survival rate of 48.4% at 2 years. Major toxicities were leukopenia and neutropenia (>/=grade 3, 92% each). The local control and overall survival demonstrated in this study were excellent. However, the insufficient distant control suggests a need for development of more active chemotherapy regimens.

[A case of bronchiolitis obliterans after allogeneic bone marrow transplantation for acute lymphocytic leukemia].

A case of bronchiolitis obliterans after allogeneic bone marrow transplantation (BMT) for acute lymphocytic leukemia in an 18-year-old woman with both acute and chronic graft-versus-host disease is described. About 160 days after BMT she started complaining of a non-productive cough and exertional dyspnea. Pulmonary function testing revealed obstructive respiratory dysfunction. High-resolution CT (HRCT) scan of the lungs showed areas of parenchymal hypoattenuation with air-trapping, which was more emphasized with expiratory HRCT. She had many of the risk factors for bronchiolitis obliterans, such as total body irradiation, pretreatment with cyclophosphamide, chronic graft-versus-host disease and a low IgG level. Her symptoms were progressive and bronchiectasis developed. She died of respiratory failure 3.5 years after BMT. Bronchiolitis obliterans is an important complication of BMT which the clinician must take into account.

[Effect of combined chemotherapy following the guidelines on treatment for Mycobacterium avium complex pulmonary disease].

We retrospectively investigated the clinical appropriateness of combined chemotherapy following the Japanese Society for Tuberculosis guidelines corresponding with those of the American Thoracic Society guideline for MAC pulmonary disease including a comparison with the past treatment for MAC pulmonary disease. The subjects of this study were 159 patients at several hospitals surveyed by the Chugoku-Shikoku Research Committee on Mycobacterium who were diagnosed as having MAC pulmonary disease between April 1995 and March 2001. Among them, 102 patients were treated using a regimen of antituberculous drugs with CAM, 33 patients received antituberculous drugs without CAM, and 24 patients were treated using other regimens. With a regimen of antituberculous drugs plus CAM, the sputum conversion rate was 45.1%, the relapse rate was 39.1% and clinical improvement was obtained in only 29.4%. On a regimen of only antituberculous drugs, the sputum conversion rate was 30.3%, the relapse rate was 70.0% and clinical improvement was obtained in 12.1%. Among the 102 patients receiving the regimen of antituberculous drugs plus CAM, 41 patients were treated with RFP, EB, SM and CAM following exactly the guidelines. The sputum conversion rate was 58.5%, the relapse rate was 37.5% and clinical improvement was obtained in 36.6%. Among 61 patients treated with other antituberculous drugs plus CAM, the sputum conversion rate was 36.1%, the relapse rate was 40.9% and clinical improvement was obtained in 24.6%. The clinical effect of the combined chemotherapy (RFP, EB, SM and CAM) was better than that of the other regimens throughout this study. However, the efficacy of this combined chemotherapy was unsatisfactory compared with the clinical effect for pulmonary tuberculosis. Therefore, the development of new companion drugs for the disease with mycobacteria other than M. tuberculosis is needed.

A phase III randomized trial comparing vindesine and cisplatin with or without ifosfamide in patients with advanced non-small-cell lung cancer: long-term follow-up results and analysis of prognostic factors.

UNLABELLED: In order to evaluate the activity and toxicity of a three-drug combination of vindesine, ifosfamide and cisplatin (VIP) for inoperable non-small-cell lung cancer (NSCLC), we conducted a randomized trial comparing VIP with a two-drug combination of cisplatin and vindesine (VP). Between September 1987 and March 1992, a total of 132 patients with stage III or IV NSCLC were randomly allocated to either VIP or VP. The VIP regimen consisted of vindesine (VDS 3 mg/m(2) on days 1 and 8), ifosfamide (IFX 1300 mg/m(2) on days 1-5), and cisplatin (CDDP 20 mg/m(2) on days 1-5). The VP regimen consisted of VDS and CDDP with the same dose and schedule as the VIP regimen. Both regimens were repeated every 4 weeks. Objective response rates were 49.3% (95% confidence interval: 95%CI, 43.1-55.4%) in the VIP arm and 44.6% (95%CI, 38.4-50.2%) in the VP arm; the difference was not significant (P=0.5390). Median response duration, median survival time, and two-year survival rates were 26.5 weeks, 49.6 weeks, and 14.9% in the VIP arm and 28.7 weeks, 37.1 weeks, and 12.3% in the VP arm, respectively. There were also no significant differences between these two treatment arms. In comparison with the VP regimen, however, a survival advantage of the VIP regimen could be confirmed when the data were evaluated with Cox's multivariate analysis (P=0.0131). In both arms, the principal toxicity was myelosuppression, which was significantly more frequent in the VIP arm, although generally well tolerated. CONCLUSION: This study suggested the survival advantage of the VIP regimen over the VP regimen for treatment of patients with advanced NSCLC.
